Answer

In patients with typical atrial flutter (tricuspid valve isthmus−dependent), catheter ablation is usually an outpatient procedure. The procedure involves moderate sedation and accessing the femoral veins for catheter insertion. The diagnosis of atrial flutter is confirmed by means of pacing maneuvers, and ablation is performed typically at the 6 o’clock position on the tricuspid valve isthmus.
